Most Americans believe Russia was behind the hacks of the Democrats during the 2016 presidential campaign. But they are divided on whether to impose further sanctions on Russia, beyond the steps President Barack Obama took last month.

An overwhelming share of the public (88%) has heard about allegations that Russia was involved in hacking the Democratic National Committee and Hillary Clinton’s campaign.

Among those aware of the allegations, 72% say Russia was definitely or probably behind the hacks, compared with just 24% who think it was definitely or probably not involved.

When asked how the U.S. should respond, nearly half (46%) of those aware of the hacking allegations say the sanctions already imposed on Russia are about right, while 27% say they do not go far enough and 20% say they go too far, according to a national survey released today by Pew Research Center.
